Everyone knows that mice like to run. In this game you have to run over a sewage duct with a funny cartoon mouse while each time solving multiplication tables. On the way, various enemies will try to stop you, and you will encounter some mean cats as well as a very angry cleaning lady. Luckily, the mouse can also run along the underside of the duct, so he can quickly get out of the way of all the dangers. Once in a while you will see an equation and an answer on either side of the duct. Only one of these two answers will be the correct answer, and if you choose the wrong one the game will end. Try to run as many yards as you can.
